Omega Constellation Ref.168.0057 Cal.1021 35.0mm 1972

Fine detailing around the white gold bezel brings depth and warmth to the Constellation Ref.168.0057. The rhythmic coin-edge texture contrasts beautifully with the flowing architecture of the case, creating a richly nuanced presence on the wrist. Inside, Omega’s automatic chronometer Cal.1021 unites the elegance of the design with the convenience of a day-date display.

In addition, this timepiece comes freshly serviced with all parts laid out by our professional watchmaker for all to see in the images above. Little to no other dealers do this and it’s a testament to full transparency here at Montre D’or. With the Cal.1021 inside running excellently as shown in the timegrapher reading above, just like it was when it left the factory nearly half a century ago.
